I mean, really, if God allowed it to take place then there was a greater good he desired more than the sufferings of these people, and if that's the case Christians should thank God for it! For the higher, greater good that came out of it was better than had it not happened at all. What was that higher good then? Even if Christians "punt to mystery" here, can they also have it both ways? Can they condemn the Holocaust and at the same time maintain there was a higher, greater good that resulted from it? I don't think so. But they can try. The question for the Christian is this one: Was it better that the Holocaust happened or not? Yes or no?
